UNITED STATES CLOTH INSPECTING MACHINE v7 Leland F. Remington, Worcester, Mass assignor to Curtis & Marble Machine Company,;Worce ster, Mass, a corporation of Massachusetts Application September 12, 1938, Serial 3 Claims. (01. 26a '79) This invention relates to machines which are used when an operator is inspecting cloth and trimming the selvage edgesthereof. My improved machine is more particularly used with cloth Woven in automatic weft replenishing looms. I

It'is the general object of my inveriti provide a machine in which the two edges piece of cloth' may be successivel veniently inspected by a single e er closely adjacent inspection static removal of the cloth from t said inspections.

A further object is to p oyid ducing selective feeding'inove'nie in opposite directions reversal, and improve con v these feeding movementsmay beware? In the preferred coinstruction of m positionon -slde iramenieriibers l I and I2. two adjacent inspection stations are indicated at A and B.

The cloth C is supplied to the machine in a roll R and is wound up in a second roll R. as

inspection of the right-hand edge thereofis completed. The cloth is then fed through the machine in the reverse direction for inspection of the left-hand edge of the cloth. During this second operation, the cloth is unwound from the roll R and is rewound at the roll R. The arrows in Fig. 2 indicate the direction of cloth travel during this second or rewind operation.

zwillgenowl' describe sthel'; improved smechan sin wh1ch I have provided for driving the winding drums and 24 and for controllingthe movements thereof. For this purpose I provide a motor M (Fig. 3) connected by chains 40 and 4| to sprockets 42 and 43v (Fig. 2) associated with clutch members 44 and 45 loosely rotatable thereon. The clutch members 52 and 53 have circumferentially grooved hub portions 54 and 55 provided with yoke members 56 and 51 having pins 58 extending through vertical slots in yoke arms 60 and GI (Fig. 2).

The yoke arm '6!) is fixed on a tube 62 movably mounted in fixed bearings 63 and 64 (Fig. 3), and the yoke arm 6| is fixed on a shaft 66, one end of which is pivotally supported in a fixed hearing 61 and the other end of which projects through and is supported by the tube 62.

A collar 10 (Fig. 3) on the tube 62 is provided with a stud H extending into a slot 12 (Fig-6) in an arm 73 secured to a cross shaft 14. A collar 16 on the shaft 66 is similarly provided with a stud 11 extending into a slot 78 (Fig.6) on an arm 19 secured to a cross tube 80. The tube 80 is mounted in a fixed bearing BI and a second and aligned tube 82 is mounted in a fixed bearing 83. The cross shaft 14 is supported in the tubes 8lland 82 andalso in a fixed bearing-84;

Pedals F and V on arms 99 and 9! are secured to the tube 82, and pedals F and V on arms 92 and 93 are secured to the crossshaft'lfl: The hub of the pedal arm 92' is interposed between the adjacent ends of the tubes Hand 82, which tubes are connected by an offset member 95.

Having described the details'of construction of my improved inspectingmachine, I will'now describe the preferred method of operation thereof.

During the first inspecting operation, the cloth is drawn from the roll'R to the roll R and travels downward over the table IS. The opera? tor occupies inspection station A (Fig. 1) and inspects the right-hand edge of the cloth; at which automatic weft replenishing has commonly occurred.

After this inspection and'after the trimmingof weft ends has been completed, the operator moves to inspection station B and inspects and trims the left-hand edge of the cloth as it is drawn up over the inspecting table ill and rewound at the roll R. Y

As there is usually very little if any weft replenishment at the left-hand edgeof the cloth, less time is required for inspection and'the cloth may be run through at higher speed. For'fthis reason, the sprocket 43 for the rewind;drum 24 is of less diameter than the sprocketJd-Zifor the drum. 2!], so that the rewind drum will rotate at higher speed and the cloth will'travel morerapid- 1y during the inspectionof the left-hand edge of the cloth whererelatively little attention or trimming is necessary.

of the right-hand pedal F will cause the drum 24 to be rotated to wind the cloth upward, and depression of the left-hand pedal V' will effect a temporary backward movement of the cloth if desired.

It will thus appear that, at either operating station, depression of the right-hand pedal causes forward movement of the cloth and depression of the left-hand pedal causes a temporary backward or reverse movement. The forward movements, however, are in opposite directions at the two stations.

My improved machine is much simplified over previous machines in which widely spaced inspection tables were provided for the two inspecting operationsand in which two operators were also required, one of Whom was only partly occupied.

In .my machine, a single operator only is required and the cloth runs at speeds proportionate to the operation being'performed;

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwisethan as setforth in the claims, but what I claim is:

1. A cloth inspecting machine having asingle inspection table, and manually-controlled power means to draw a piece ofcloth over said table in forward andreverse directions for'successive inspection of opposite selvages, said-powermeans comprisingspaced winding drums supportingand rotating rolls of cloth which'remaim in continuous contact therewith, a continuously rotated drive shaft operative to rotate'one of said drums in one direction and the other drum in the opposite direction, and. manually'movable means effective to connect either selected drum-tosaid drive shaft and to simultaneously disconnct the other drum.

2. A cloth inspecting machine having a single inspection table, and manually-controlled power means to draw'a piece ofcloth over said table in forward and reverse'directions for successive inspection of opposite selvages; said machine hav ing two pairsof control pedals each-comprising forward and reverse pedalsdefining an inspection station for a selected selvageyandthe forward pedals in said two pairs being inthe'same relative position to the reverse pedalsbut'causing the cloth to move-oppositelyover the inspection table.

3. In a machine for inspecting clothwoven-in an automatic weft-replenishing loom, a single cloth inspection table, power means to draw 'a piece ofcloth over said table in one direction at a predetermined speed for inspection of the mag azine' selvage, powermeans to" draw'a piece 'of cloth over said table in the opposite direction and at a substantially higher predetermined speed for inspection of the "non-replenishing selvage, and manual means to make 'saidfirst and second power means selectively operative.
